Restore Full Electrical Function to Your GM Truck or SUV
Is your 2012-2014 GM vehicle acting possessed? Flickering lights, intermittent power windows, a security system that won’t cooperate, or a battery that drains overnight are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, managing everything from interior lighting and power locks to the instrument cluster and security system. When it fails, it can cause a cascade of frustrating and seemingly unrelated electrical problems.
This isn’t just an inconvenience; a faulty BCM can leave you stranded. Don’t let electrical gremlins dictate your vehicle’s reliability. This direct-replacement Body Control Module is the definitive solution to restore your vehicle’s electronic systems to perfect working order. We take the guesswork and dealership hassle out of the equation. Simply provide your vehicle’s VIN during checkout, and we will program the module with the latest GM software specific to your truck or SUV. It arrives at your door ready for a straightforward installation.
From the Diagnostic Bay
We had a 2013 Silverado 2500 in the shop with a classic parasitic battery drain. The owner had already replaced the battery twice and the alternator once, but every few days, the truck would be dead. After hours of tracing circuits, we isolated the draw to the BCM. It wasn’t fully going to ‘sleep’ when the truck was off, slowly draining the battery. A new, properly programmed BCM solved the problem instantly. It’s a common issue that often gets misdiagnosed, costing owners hundreds in unnecessary parts.
Symptoms of a Failing 2012-2013 Escalade EXT BCM
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your Body Control Module is the culprit:
- ✔ Unexplained battery drain, even with a new battery.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Vehicle security system faults or anti-theft light staying on, preventing the engine from starting.
- ✔ ‘Service StabiliTrak’ or other warning messages appearing on the dash.
- ✔ Remote keyless entry failing to operate correctly.
Plug-and-Play Solution
The biggest hurdle in replacing a BCM is the complex programming required to sync it with your vehicle’s specific options and security systems. We eliminate this step for you. Our service includes flashing this module with the most current GM-approved software, matched precisely to your VIN. This ensures that when you receive the part, it’s ready to be installed without the need for an expensive trip to the dealership for programming.
Installation and Post-Install Notes
The BCM is typically located under the driver’s side of the dashboard, near the steering column. Physical installation is a matter of disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. However, please be aware of potential post-installation procedures:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. A ‘Setup SDM Primary Key in BCM’ procedure will need to be performed with a professional scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: A brake pedal position sensor relearn might be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
